A Phase 1 interventional study of ALZ-801 170 mg Fasting and ALZ-801 205 mg Fasting in Alzheimer Disease, sponsored by Alzheon Inc.. Completed. Open to participants aged 18 Years to 65 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2020-10-14.
Sponsored by Alzheon Inc. · Phase 1, Interventional, and Treatment
Phase 1, single-center, open-label, non-randomized, sequential single dose 4-period study in 12 healthy subjects to assess the pharmacokinetics of ALZ-801, tramiprosate and the primary metabolite of tramiprosate, NRM5074, from prototype drug product formulations of ALZ-801, and to assess effect of food on the bioavailability of ALZ-801 and tramiprosate of the prototype tablet formulation.
This is a single-center, open-label, non-randomized, sequential, single-dose, 4-period study in 12 healthy adult subjects. Subjects are to receive a single oral dose of ALZ-801 in each of the 4 study periods (Regimens A, B, C and D) in a non-randomized, sequential manner, separated by a minimum washout period of 7 days. The washout period is expected to last approximately 14 days to permit interim decisions to take place and to allow for the selection of the formulation of the subsequent regimen. Periods of interim analysis will take place following dosing with prototype formulations Regimens A, B, and C, during which the PK and safety data are reviewed to determine the dose to be administered in the subsequent treatment period. Interim decisions aim to identify a prototype ALZ-801 immediate release tablet formulation that provides a similar tramiprosate AUC and Cmax to that of historical values after administration of a 100 mg loose-filled tramiprosate capsule in the fasted state.
Optimization of the required tramiprosate exposure will be made by adjusting the dose of ALZ-801 in the prototype tablets using a formulation design space with a target dose range, per tablet, of 171 to 514 mg ALZ-801 (equivalent to 100 mg to 300 mg tramiprosate). Dose selection will be made after a complete review of all data collected from the previous dose group. For dose selection to occur, data is required to be available from a minimum of 8 evaluable subjects with complete safety assessments up to 24 h post-dose, and required safety and PK data (AEs, plasma concentrations of ALZ-801, tramiprosate and NRM5074, and Tmax, Cmax and AUC estimates for ALZ-801 and tramiprosate).

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Ran from Sep 2015 to primary completion in Nov 2015, 1 month.
Of 160 industry-sponsored phase 1 interventional studies under Alzheimer Disease, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 23. This study's 1 month is below that.
Counting every sponsor, half of 233 studies reached it within 18 months; a quarter within 7 and three quarters within 39.
